7 Claims.

This invention relates to sliding doors for railway cars and concerns itself more particularly with such doors constructed to receive a wooden lining.

It is an object of this invention to provide a sliding car door having a wooden lining, the structure of the door being such that the lining may readily be removed from and applied to the door while the door is mounted upon the car.

A further object is to provide a sliding car door having a wooden lining, the door'being characterized by the fact that no increase in the number of fastening means utilized in the door is required for the securement of the lining and by the further fact that the fastening means are disposed in the same positions in the door as in the case of a door without a lining, so that additional holes in the door are avoided.

A further object is to provide a door having a wooden lining, the door being so constructed that means utilized to secure the lining is incorporated with the door in such manner as to reinforce the door.

Other objects of the invention will become clear as the description thereof proceeds.

In the drawings forming part of this specification Figure 1 is a fragmentary elevation of a railway house car having applied thereto a door embodying the instant invention;

Figure 2 is a vertical section taken on line 2-2 of Figure 1;

Figure 3 is a horizontal section taken on line 33 of Figure l; and

Figure 4 is a horizontal section taken on line 4-4 of Figure 1.

Referring to the drawings which illustrate a preferred embodiment of the invention, the numeral i i) designates a railway house car which is provided with the customary door opening, defined along its vertical boundaries by means of front and rear door posts H and i2 and along its upper and lower boundaries by means of a side plate 53 and a floor I4. The opening thus defined is adapted to be controlled by means of a door It comprising a metallic panel It, which may be provided with a plurality of spaced horizontal corrugations ii and vertical corrugations l8 and IS with which the horizontal corrugations may merge. The front and rear vertical margins of the panel are reinforced by means of the vertical reinforcing members 20 and 2| while the upper horizontal margin of the panel is reinforced by means of the member 22.

The door is adapted to be Supported for move- 1934, Serial No. 722,610

ment upon the car it) upon a track 23 supported from a side sill 24 by means of a plurality of brackets 25. Antifrictional movement upon the track is provided for the door through the agency of hangers 26 and 27 carrying roller bearing roll- 5 ers 28 disposed in rolling engagement with the track 23. The hangers 26 and 21 are provided with upwardly extending flanges 29 which are disposed in overlapping engagement with a de pending flange 38 provided on the track 23 in 10 order to avoid disengagement of the lower portion of the door from the track. At its upper margin the door is maintained upon the car and guided in its movements upon the track by means of the interengagement between a depending l5 flange 3! provided on a retaining bar 32 secured to the depending leg 33 of the side plate 13 and the upwardly extending flange 34 provided on the horizontal reinforcing member 22. Clips 35 and 36, secured to the upper margin of the door, 00- 20 operate with the depending flange 3! of the retaining bar to prevent undue movement of the upper margin of the door toward the car.

An Opening and closing arrangement, indicated in its entirety by the reference numeral 31, 26 may be utilizedin conjunction with the door and a locking device, indicated as a whole by the numeral 38, may be utilized in order to fasten the door in its closed position.

The metallic door hereinabove described is de- 10 signed to receive a wooden lining and for this purpose applicants novel construction is utilized. There is, consequently, provided upon the front vertical margin of the door a member 39 preferably Z shaped in section which is secured upon 35 the inner face of the door by means of the same rivets utilized to fasten the vertical reinforcing member 25! to said door. As clearly illustrated in Figure 3 of the drawings the member 20 is also preferably 2 shaped in section, one of the longitudinally extending flanges 40 thereof being adapted to cooperate with a channel shaped formation il provided on the front door post H in order to stop the closing movement of the door and to provide a weather protection therefor. Each of the members 20 and 39 are so disposed that their respective webs 42 and 43 extend inwardly and transversely of the door and, together with the disposition of the securing flanges of said members, constitute a reinforcing chan- B0 nel for the front margin of the door, whereby said front margin is materially strengthened to resist impact between the reinforcing member 20 and the door post H. The longitudinally extending figmgg v44 of the member 39 is disposed as shown 5 versely and inwardly extending Webs 46 and 41 of the members 22 and 45, together with the over-,

7 front, upper and. lower margins of said lining.

lapping flanges of said members, provide a substantially channel shaped section for the upper margin of the door.

parallel relationship with. the panel |6 of the door. V r .1

A Z shaped member .49 is secured uponthe inner face of the panel at the lower ,margin thereof. The'member 49serves to reinforce the lower margin of the door and by virtue of its disposition with the web 50' thereof extending inwardly transversely of the door the upwardly extending flange 5| of said member lies in spaced parallel relationship to the panel ofthe door.

. The Z shaped members 39, 45 and 49 are so arranged upon the inner face of the metallic panel |6 that the flanges 44,48 and 5| thereof lie in substantially the same plane.

A wooden lining 52 isadapted to be provided upon thein'ner'face of the door l5, being maintained upon said door by the freely overlapping V engagement of the flanges 44, 48 and 5| upon the The lining extends rearwardly beyond the door post I2 and terminates substantially with the rear edge of the panel. The reinforcing member 2| of the door, which preferably is secured to the panelby means of rivets 53 independently of said lining, may comprise an angle member one leg 54 of which extends transversely and inwardly of said panel so as to lie across the'rear edge of the lining. A sealing strip 55, adapted to coaot with r a spark strip 56 provided on the rear door post 2,

is secured to the door as by means of bolts 51, said sealing strip being disposed upon the wooden lining as clearly illustrated in Figures 1 and 4 of the drawings. I The rear marginal portion'of the wooden liningmay'be notched out as indicated gin of the door independently 'of' the wooden It will be readily apparent that the 'wooden lining 52 is securely maintained upon the inner face of the door. It will also be apparent that said lining may be removed from and a new lining applied to the door without the necessity of first removing the door from the car. If

I securing bolts are used'to fasten both the reinbers and subsequently bolting the reinforcing member 2| and the sealingstrip 55 upon the rear marginofthe'door, these'bolts extending through the" wooden lining. However, as preferred; the reinforcing member 2| is riveted to the rear marlining'whilethesealing strip 55 is bolted to the door by means of bolts .extending'through the lining. To remove a'damaged lining it becomes necessary to remove the bolts 51' and the rivets V 53; In the replacement of this lining it'is first slidably engaged with the members 39, 45 and 49, after which the reinforcing member 2| is riveted therefore, that all such modifications The downwardly extending flange 48 of the Z shaped member 45 lies in spaced ing strip 55 is bolted to the wooden lining and the 5 door.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended,

changes becomp-rehended within this invention,- which is to be limited only by the scope of the claims appended hereto.
